Die Erfindung betrifft ein Filter zum Reinigen der Luft für nach außen abgeschlossene Räume, insbesondere in Fahrzeugen, dessen Filterbehälter durch eine Zwischenwand in zwei herausnehmbare Schwebstoff- und Gasfiltereinsätze aufnehmende Räume unterteilt ist, von denen der Raum, in dem der Schwebstoffiltereinsatz untergebracht ist, eine durch einen Deckel abschließbare Öffnung zum Herausnehmen des Einsatzes aufweist.The invention relates to a filter for cleaning the air for rooms closed off from the outside, in particular in vehicles, the filter container of which is divided into two removable spaces for suspended matter and gas filter inserts through a partition is divided, of which the space in which the HEPA filter element is housed, one through has a lid lockable opening for removing the insert.
Es ist ein Filter zum Reinigen der Luft für nach außen abgeschlossene Räume bekannt, dessen fahrbarer Filterbehälter aus zwei aufeinandergesetzteh Teilen besteht. Der Behälter ist durch eine Zwischenwand in zwei Räume unterteilt, die übereinanderlier gen. In dem unteren Raum, an dem der Luftaustrittsstutzen angeschlossen ist, sind Aktivkohle enthaltende Gasfiltereinsätze untergebracht. Die mit Aktivkohle gefüllten, durch Öffnungen in der Zwischenwand greifenden Filtergehäuse sind am oberen Ende mit einem nach außen ragenden Flansch versehen, mit ao dem sie an der' Zwischenwand angehängt sind, an der sie mit Befestigungsschrauben befestigt sind. Die Zwischenwand ist mit einem dem oberen Abschlußrand des unteren Behälterteils aufliegenden Befestigungsrand versehen. Der über dem unteren Behälter- as teil angeordnete obere Behälterteil ist an seinem unteren Ende mit einem Flansch versehen und liegt mit diesem dem Befestigungsrand der Zwischenwand auf. Am entgegengesetzten Ende ist der obere Behälterteil ebenfalls mit einem Flansch versehen, auf dem eine weitere Zwischenwand abgestützt ist, die mit Durchbrechungen versehen ist, die zum Einhängen der Gehäuse dienen, die die Schwebstoffiltereinsätze enthalten. Diese Gehäuse sind auch.jeweils mit einem Flansch versehen, der der oberen Zwischenwand aufliegt und mit dieser verschraubt ist. Der obere Behälterteil ist durch einen mit einem Flansch versehenen ,Deckel- verschlossen, der auf dem Rand der Zwischenwand aufliegt. Der Deckel ist mit einem mittigen Stutzen zum Anschluß der Ansaugleitung versehen. Wenn bei diesem Filter die Schwebstoffiltereinsätze ausgewechselt werden sollen, muß zunächst die Verbindung zwischen dem Anschlußstutzen des Deckels und der Ansaugleitung gelöst und der Deckel abgenommen werden. Darauf können die Schwebstoffiltereinsätze herausgenommen werden. Wenn die Gasfiltereinsätze ausgewechselt werden sollen, muß der obere Behälterteil vom unteren gelöst werden. Es ist bei dem bekannten Filter somit nicht möglich, die Gasfiltereinsätze herauszunehmen, ohne nicht den oberen Behälterteil zu lösen und abzunehmen. Das ist insbesondere bei Filter zum Reinigen der LuftThere is a known filter for cleaning the air for rooms closed off from the outside, the mobile filter container of which consists of two parts placed one on top of the other. The container is divided by a partition into two rooms, the übereinanderlie r gene. In the lower space where the air outlet port is connected are housed gas filter elements containing activated carbon. The filter housings filled with activated carbon and reaching through openings in the partition are provided at the upper end with an outwardly protruding flange with which they are attached to the partition to which they are attached with fastening screws. The intermediate wall is provided with a fastening edge resting on the upper end edge of the lower container part. The upper container part arranged above the lower container part is provided at its lower end with a flange and with this rests on the fastening edge of the partition. At the opposite end of the upper container part is also provided with a flange on which a further partition is supported, which is provided with openings which are used to hang the housing containing the particulate filter inserts. These housings are also each provided with a flange which rests on the upper partition and is screwed to it. The upper part of the container is closed by a cover with a flange and resting on the edge of the partition. The cover is provided with a central nozzle for connecting the suction line. If the HEPA filter inserts are to be replaced in this filter, the connection between the connection piece of the cover and the suction line must first be released and the cover removed. The particulate filter elements can then be removed. If the gas filter inserts are to be replaced, the upper part of the container must be detached from the lower part. With the known filter it is therefore not possible to remove the gas filter inserts without loosening and removing the upper container part. This is especially true for filters that purify the air

Verwendung des Filters zum Reinigen von mit radioaktiven Gasen verseuchter Luft nachteilig, zumal da die Gasfiltereinsätze im allgemeinen häufiger als die Schwebstoffiltereinsätze ausgewechselt werden müssen. Es besteht dann die Gefahr, daß radioaktive Luft in die Umgebung des Filtergehäuses gelangt. Dieselbe Gefahr besteht, wenn ein Schwebstoffiltereinsatz ausgewechselt und dazu der Behälterdeckel ausgebaut werden muß. Dann können ebenfalls radioaktive Stäube in die Umgebung des Filterbehälters gelangen.Using the filter to clean with radioactive Gases contaminated air disadvantageous, especially since the gas filter inserts in general more often than the particulate filter elements need to be replaced. There is then a risk of being radioactive Air gets into the vicinity of the filter housing. The same danger exists when a particulate filter element and the container lid are replaced must be expanded. Then radioactive dusts can also get into the vicinity of the Reach the filter container.
Es ist weiterhin eine Lüftreinigungsvbrrichtung bekannt, in deren Behälter eine Luftfördervorrichtung und mehrere herausnehmbare Filter untergebracht sind. Die Filter haben etwa die Gestalt rechteckiger Kästen, die an der Ober- und an der Unterseite offen sind und mit ihren Seitenwänden aneinanderliegen. In den Kästen sind als Filtereinsätze Reinigungszellen untergebracht, die Schwebstoffilter enthalten bzw. mit Aktivkohle oder anderen geeigneten Reinigungsmitteln gefüllt sind: Nach Lösen der Stirnwand des Behälters können die Kästen herausgenommen werden. Bei dieser bekannten Vorrichtung können die Zellen nur gemeinsam ausgetauscht werden. Es ist,also nicht möglich, die Filtereinsätze einzeln auszutauschen. Dies ist nachteilig, weil unterschiedliche Filtereinsätze nicht immer gleichzeitig ausgewechselt werden müssen.It is also a ventilation cleaning device known, in the container of an air conveyor and several removable filters are housed. The filters have roughly the shape rectangular boxes that are open at the top and bottom and with their side walls lie against each other. There are filter inserts in the boxes Housed cleaning cells that contain particulate filters or with activated carbon or other suitable cleaning agents are filled: After loosening The boxes can be removed from the front wall of the container. In this known device the cells can only be exchanged together. It is, therefore, not possible to use the filter inserts to be exchanged individually. This is disadvantageous because different filter elements are not always available must be replaced at the same time.
Der Erfindung liegt die Aufgabe zugrunde, ein Filter, insbesondere für Fahrzeuge, zu schaffen, dessen Filtereinsätze verhältnismäßig schnell und einfach ausgewechselt werden können und bei dem ein Auswechseln des Gasfiltereinsatzes ohne die Gefahr der Verseuchung der Umgebung möglich ist. Die Lösung besteht darin, daß die Halterung des oder der Gasfiltereinsätze, derart ausgebildet ist, daß die Einsätze in Richtung zu dem sie aufnehmenden Raum lösbar sind, der mit durch Abschlußdeckel abschließbaren Öffnungen zum gesonderten Herausnehmen des oder der Gasfiltereinsätze versehen ist. Das erfindungsgemäß ausgebildete Filter hat den Vorteil, daßThe invention is based on the object of providing a filter, in particular for vehicles, of which Filter inserts can be exchanged relatively quickly and easily and in which an exchange of the gas filter insert is possible without the risk of contaminating the environment. The solution consists in the fact that the holder of the gas filter insert (s) is designed in such a way that the inserts are releasable in the direction of the space receiving them, which can be locked with a cover plate Openings is provided for the separate removal of the gas filter insert (s). That according to the invention trained filter has the advantage that
